CALCulate<Chn>:TRANsform:DTFault:DEFine <CblName>, <CblPermittivity>,
Defines a new user-defined cable type for Distance to Fault (DtF) measurements.
The cable's frequency-dependent attenuation is defined via attenuation/frequency pairs
<CblAtt1>, <CblFreq1>, <CblAtt2>, <CblFreq2>, ... . At least one pair
has to be specified.

Channel number
This suffix is ignored: cable types are defined for all channels.
Name of the cable type.
Must be unique among all DtF cable types, with case insensitive
match.
Relative permittivity ε
Attenuation value i in the frequency-dependent attenuation table
of the cable type.
Default unit: dB/m
Frequency i in the frequency-dependent attenuation table of the
cable type.
Default unit: Hz
CALCulate:TRANsform:DTFault:DEFine 'My cable
type', 1.1, 0.01, 1GHz, 0.015, 2GHz, 0.012,

Defines a new cable type "My cable type" with relative permittiv-
ity ε =1.1 and the frequency-dependent attenuation given in the
